Staring at mobile phones is putting children at risk of blindness.
Staring at phones makes children go blind
Kids as young as four in Britain are wearing special contact lenses to counter the growing issue and doctors are seeing more teenagers with the worst scores for short-sightedness.
It is suspected that the issue is a result of children straining to look at their smartphones while not spending enough time outside.
Dr. John Bolger, director of a private eye clinic in London, told the Mail on Sunday newspaper: "There are more and more myopic children coming into the clinic. It's going up and up. There's no slowing down from what I can see.
"Myopia is not just having to wear glasses, people can go blind from myopia. This is not a trivial event, this is a serious threat."
